Del Potro back to Argentina to recover

World No. 7 Juan Martin del Potro returns to Argentina to embark on an intensive physical recovery program in order to ensure his participation in Roland Garros, his team said in a statement. Del Potro has been troubled by a bronchial infection since Monte Carlo, which forced him to pull out of Estoril and Madrid. His doctor, Roberto Peidro, said the rest period failed to achieve substantial results and his condition began to worsen in Rome, where he lost to Benoit Paire.
